        <p>
      This opcode writes vectors to tables at init time.

        <h2>Syntax</h2>
        <pre class="synopsis"><span class="command"><strong>vtabwi</strong></span>  indx, ifn, inarg1 [, inarg2, inarg3 , .... , inargN ]</pre>
      </div>

        <a id="idp167409184"></a>
        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>indx</em></span> - Index into f-table, a positive number range matching the table length
      </p>
        <p>
      <span class="emphasis"><em>ifn</em></span> - table number
      </p>
        <p>
      <span class="emphasis"><em>inarg1...inargN</em></span> - input vector elements
    </p>
      </div>
      <div class="refsect1">
        <a id="idp167412416"></a>
        <h2>Performance</h2>
        <p>
      This opcode is useful in all cases in which one needs to write sets of values associated to unique indexes (for example, multi-channel samples, STFT bin frames, spectral formants, p-field based scores etc.). The number of elements of each vector (length of the vector) is determined by the number of optional arguments on the right (<span class="emphasis"><em>inarg1</em></span>, <span class="emphasis"><em>inarg2</em></span>, <span class="emphasis"><em>inarg3</em></span>, ....  <span class="emphasis"><em>inargN</em></span>).
    </p>
        <p>
      Notice that no wrap nor limit mode is implemented.  So, if  an index attempt to access to a zone not allocated by the table, Csound will probably crash. However this drawback can be easily avoided by using wrap or limit opcodes applied to indexes before using <span class="emphasis"><em>vtabwi</em></span>, in order to correct eventual out-of-range values.
